It does not matter if you are a Doctor, a Lawyer or an infantry soldier in the Army if you want to be the best and get ahead, you will need to take risks.
A doctor may have to take risks when working with a patient. The Doctor may have to experiment with different forms of medications or new surgical procedures when all else has failed in an attempt to help the patient.
A lawyer may have to argue a case in an unorthodox manner to win the case, but if the lawyer wants to become the top lawyer and make millions of dollars fighting high profile cases lots of risks have to be taken.
A soldier may have to take a risk and run thru gunfire to save another injured soldier, to complete their mission, or just to secure an area from being overrun by enemy troops, after going days with little to no sleep, but if a soldier wants to get promotions and eventually lead men into battle they also need to take risks.
These risks are not unlike someone looking to get rich in a casino, they have to be willing to risk everything they have to get that million dollar payoff. If you play it safe in a casino you may get lucky and win a big jackpot on the slot machines, but if you want to make millions you are going to have to play games such as Poker, Blackjack, Roulette and craps. These are the games that with some skill, some luck and a lot of risk taking you can retire off your winnings.
The same can be said about life in general. No one gets ahead in life from playing it safe. You will not meet your special someone if you are too afraid to risk getting rejected by someone, you will never get that big promotion unless you take risks at your job.
It is very important to continue to take risks in life. To stop taking risks means to stand still in life. Standing still in life is one of the main causes of depression. These are usually the people afraid to confront the boss and tell him that they demand a raise; they are the ones that allow life to pass them by out of fear. The entire purpose of fear is to stop you from taking a risk.
Fear is nothing more then the unknown. If you have always wanted to quit your job and open a shop but you are too afraid to do it, this is because you are afraid of failing and risking what you already have.
It is important to learn to take risks in life if you want to be happy, you may not always get the things you risked for, but you will know that you tried, and in the end it does not matter in my opinion if you succeed or not it is how many risks you try to make that is the real test of how successful you are.
Just remember if no one took risks we would be a world without flight and probably no automotive vehicles at all, maybe we would have no electricity. So risk truly is needed to improve the world.
